While it's important to accept failure and not let it bog you down, it's also perfectly acceptable to get upset about it as long as you remember that failure is a stepping stone in your journey that is getting you to where you need to be.

I feel rejecting rejection is one of the most crucial steps in getting past failure.

In order to handle rejection, we have to reflect on the past, analyze/study it. Next, just like a computer, we have to reboot. Next, get it out of our system by rejecting every aspect of it.
